Both acts appeared on the NME Awards Tour in February this year and will bring their live shows to the Scottish festival when it returns next year. They join headliners The Killers, Rihanna and Mumford & Sons on the line-up.
As confirmed earlier this week, The Killers are set to headline next summer’s T In The Park. The 20th anniversary of the Scottish festival previously confirmed headline slots for both Rihanna and Mumford and Sons and will also see sets from Alt-J , Jake Bugg, Paloma Faith and Of Monsters And Men.
The Killers previously headlined the event in 2007 and 2009. Tickets for the festival go on sale at 9am (GMT) Friday, December 7. A limited number of tickets will be on sale at 2012 prices.
